ARTHUR E. SINGLETON ATTORNEY Patented Aug. 18, 1953 CHILDS AUXILIARY SEAT ATTACHMENT Arthur E. Singleton, Fort Wayne, Ind., assignor to The Toidey Company, Gertrude A. Muller, Inc., a. corporation of Indiana Application October 16, 1947, Serial No. 780,171

7 Claims.

This invention relates to improvements in a childs auxiliary seat attachment for an adults toilet, in which an adjustable foot-rest is included together with locking means for securing the toot-rest in selected positions relative to the auxiliary seat.

An object of the instant invention is to provide a childs toilet seat with a foot-rest adjustably supported in connection therewith, and a locking means for the foot-rest concealed beneath the seat out of reach of the occupant but accessible for manipulation by the attendant.

Another object of the invention is to provide dual locking means for foot-rest supporting rods in a toilet seat adapted for simultaneous manipulation.

Other objects and advantages of the invention appear in the following description.

An illustrative embodiment of the invention is shown in the accompanying drawings, in which:

Fig. 1 is a side elevational view of a structure in which the invention is incorporated;

Fig. 2 is a bottom plan view of the structure shown in Fig. 1, parts being omitted; and

Fig. 3 is a fragmentary bottom plan view, drawn to an enlarged scale, showing one of the locking devices.

The illustrative embodiment of the invention consists preferably of a molded form of plastic material shaped to provide a seat 5, armrests 6 and a back-rest I. The underside of the seat 5 is hollow in that it has an outer marginal downwardly extending flange 3 and an inner downwardly extending flange 9 surrounding the toilet opening It, and in connection with the seat is arranged a foot-rest I I supported on sliding rods l2 that have longitudinal movement through the outer marginal flange 8 and guides I3 and It conveniently located within the hollow seat, there being openings provided in said guides through which said rods extend, and stops I2 to limit movement thereof.

A locking mechanism is provided in the seat for each of the rods I2 whereby to prevent axial movement of the rods in either direction, one locking mechanism being the counterpart of the other. Each lockin mechanism consists of an operating lever I5 having a perforated angular portion I6 through which the corresponding supporting rod I2 extends, and a perforated locklever I1 mounted on said supporting rod I2 provided with an angular finger or abutment I8 that has engagement with the operating lever when the latter is moved into unlocking position. The guides I3 and It have opposing lugs I9 and between which the extension It and the locklever I I extend and are confined in operating position therebetween by staples 2| secured in said lugs. The lock-lever I'l bears against the lug I9 which constitutes a fulcrum therefor, and the outer end of the extension I6 rests upon a projection 22 of the guide I3 which constitutes a fulcrum for the operating lever.

Disposed loosely upon the rod 52, concentric therewith, is a compression spring 23 that bears oppositely against the opposing faces of the extension and lock-lever, and tends to move said extension and lock-lever into locking engagement with the corresponding rod I2. The openings in the extension and lock-lever are such as to permit freedom of movement of the rod therethrough when moved to positions at right angles thereto, and sufiiciently snug as to cause binding of the extension and lock-lever upon the rod when the lock-lever is released by the operator. Thus, the foot-rest may readily be moved into selected positions when the levers are depressed, and become locked in such positions due to the reaction of the springs, when the levers are released by the operator.

The seat is equipped with a downwardly extending spring hook 24 and stops 25 by which the appliance is secured to and centered upon an adult toilet seat (not shown) as in the usual manner.

In use, the foot-rest is adjusted by first press- 7 ing the operating levers I5 toward each other,

. of the springs 23 until said extensions and the corresponding lock-levers are disposed at right angles to the supporting rods I2, thus permitting the rods to be axially moved freely in either direction as may be desired while adjusting the foot-rest relative to the seat structure. Upon releasing the operating levers, the extensions thereon and the lock-levers reassume their normal locking positions by the reactionary force of the springs, thus securing the foot-rest sup ported on the rods in the position to which it has been adjusted.

A feature of the invention is the arrangement of the operatin levers and the lock-bars in the seat and their connections with the supporting rods for the foot-rest, whereby the rods are normally locked against axial movement in the seat in either direction, or unlocked simply by simultaneously pressing the operating levers thus to permit adjustment-of the foot-rest.

Variations from the particular construction above disclosed may be resorted to by the exercise of skill in the art. without departure from the spirit or scope of the invention.

What I claim is:

1. An infants toilet seat comprising a substantially flat base having spaced lateral sides, a pair of spaced guide; flanges supported by said base on each of said sides and having aligned openings therethrough, two parallel extending rods carried by said base, a foot-rest carried on:

the common ends of said rods, each rod recipro.-

cably received by the openings of a respectivepair of said flanges, two lock-ing levers. supported between each pair of spaced flanges and. having openings through which the respective rod is re ceived, a spring surrounding each rodbetween the respective levers tending to urge the levers apart, a fulcrum provided on one of each pair of flanges and engageable by one of each pair of levers whereby each spring will urge each said. one lever into lockingengagement with the respective rod, and two operating portions of the other levers extending inwardly from said base sides and conjointly operable toengage and pivot said one of each pair of levers about the. respective fulcrums to compress said springs and one look said rods for movement with. respect to. said base.

2. An infants toilet seat comprising a substantially fiat base having spaced lateral sides, a pair of spaced guide flanges. supported by said base on each of said sides and having aligned openings therethrough, two parallel extending rods carried by said base, a foot-rest carried on the common ends of said rods, each rod reciprocably received by the openings of a respective pair of said flanges, two locking levers supported between each pair of spaced flanges and having openings through which the respective rod is received, spring means carried by each rod be tween the respective levers tending to urge the levers apart, a fulcrum provided on one of. each pair of flanges and engageable by one of each pair of levers whereby each spring means will urge each said one lever into locking engagement with the respective rod, and two operatingv portions of the other levers extending. inwardly from said base sides and conjointly operable to engage and pivot said. one oi each pair of levers about the respective iulorums. to. release said spring means and unlocksaid rodsfor movement. with respect to said base.

3. An infants toilet seat comprising asubstantially flat base having spacedlateral sides, two parallel extending rods reciprocably carried by said base, a foot-rest supported by said rods, and locking means on said base arranged. to lock said rods in a selected position and comprising guide means for each rod adapted to limit the movement of each rod to longitudinal movement only, two locking levers associated with each guide means and adapted to grip the respective rod for looking it against movement with respect to said base, each guide means providing a fulcrum for one of said levers, and means supported with respect to said base and yieldably urging said one lever into gripping engagement with the respective rod, the other of said locking levers having portions extending inwardly of said base which may be simultaneously operated to engage with said one levers respectively whereby the latter are pivoted about the respective iulcrums against the force of said yieldable means to release said rods for movement.
